I realize this thread is 4 months old, but I have a question that feels related.
Background
I migrated from ST to a Hubitat C7 hub with firmware version 2.2.4.158 a few weeks ago and I was having a lot of problems with delayed and lost events. All involved devices were Z-Wave.
While carefully experimenting with 1 set of changes at a time, I noticed that I had 2 Honeywell-Jasco switches that I had included with "Security=None". They were located together in a 2-gang box. A third Honywell switch, located about 5-10 feet away was included with "S2 Unauthenticated". After excluding & resetting the 2 "Security=None" switches and then re-including them with "Security=S2 Unauthenticated", everything stabilized. It was a dramatic improvement!
Prior to the change it would take a long time after a hub reboot for the routing tables exposed by @tony.fleisher's excellant Z-Wave mesh tool to populate, and many of the routes seemed very circuitous. After the change, those routes were showing up in just a few minutes and they seemed much more reasonable.
My questions
- Is there a well-understood reason why the change from security="None" to "S2 Unauthenticated" should have such a dramatic improvement in my network stability?
- I have 1 Zooz ZEN30 that I have included as "Security = None" based on these posted instructions from the Zooz folks. While it is working reliably, it has the worst "LWR RSSI" measure (15db) of all my devices, shows the hub as it's only neighbor despite another device that is closer showing the Zen30 as a neighbor and can never be successfully "repaired". Could this be related to the use of "Security=none" vs. "Security=S2 Unauthenticated"?
Thanks in advance for any insights you can provide!
Marc
